Far from “Disappointing”

Disappointing results from Nova Vision's visual restoration therapy.

L esions posterior to the optic chiasm produce homonymous visual field loss—overlapping scotomas in the nasal field of one eye and the temporal field of the other eye. Patients retain normal acuity, but find their lives changed forever. A homonymous hemianopia, when complete, makes safe driving impossible and reading a chore. Although some patients experience partial, spontaneous improvement fo...

Why Have Climate Negotiations Proved So Disappointing?

Isotropization far from equilibrium

Isotropization occurs on time scales much shorter than the thermal equilibration time. This is a crucial ingredient for the understanding of collision experiments of heavy nuclei or other nonequilibrium phenomena in complex many body systems. We discuss in detail the limitations of estimates based on standard “linear” or relaxationtime approximations, where isotropization and thermal equilibrat...

Far-from-equilibrium computation

We study the possibility of developing far-from-equilibrium computational systems, in analogy with corresponding self-organizing physical systems. We review the computational models developed in analogy with physical systems converging towards equilibrium and the research related to the self-organization of far-from-equilibrium physical systems. Based on this review, we define several nonequili...
